pub struct IfModifiedSince(pub HttpDate);

[−] Expand description

If-Modified-Since header, defined in RFC7232

The If-Modified-Since header field makes a GET or HEAD request method conditional on the selected representation's modification date being more recent than the date provided in the field-value. Transfer of the selected representation's data is avoided if that data has not changed.

ABNF

If-Unmodified-Since = HTTP-date

Example

use hyper::header::{Headers, IfModifiedSince};
use std::time::{SystemTime, Duration};

let mut headers = Headers::new();
let modified = SystemTime::now() - Duration::from_secs(60 * 60 * 24);
headers.set(IfModifiedSince(modified.into()));
